Stock Bike "Flebi Supra" Hub Motor Upgrade

[akarl]

Hello,

Ive got a quick question. Im quite sure this was asked before but I couldnt find anything.

I have the mentioned folding ebike with a hub motor.
Is it possible to swap the motor with a bigger one like 500W? If yes, do I need to change anything else?

Its (relevant) specs are:
Voltage (V) 100-240 VAC
Battery Samsung 36V/11.6Ah LiOn, USB, security lock
Motor Aikema AKM-13.0 Geared Brushless 36V/250W
Display LED panel 3 assistance level and battery control (LCD Bigstone C300S optional)
Controller KT 36v
PAS Sensor Speed senser, 3 assistance level
Charger SANS Electronic 42.0V 2.0A EU plug

Thanks a lot,
karl

IT depends on what you're trying to do; are you fixing a problem or just wanting to upgrade for some reason?

Unless you also change the controller to one that can output the power you need from the motor, and a battery to support the new higher power demand without too much voltage sag or loss of range (or even damaging it), there's no point to changing the motor.

If the existing controller is overheating the existing motor on hills, etc., then a bigger motor would potentially not overheat, but it may not behave any differently than that.

If you're after higher speed, a higher wattage motor won't directly make any difference, unless it also spins faster than your existing one.


As a note, folding bikes often have smaller wheels and narrower dropout spacing than regular bikes, so you also have to be sure the new motor will fit, by checking what you already have and getting new one with teh same width/spacing.

http://ebikes.ca has motors/wheels spaced for some of the narrower folding bikes, along with controllers and batteries, etc.

Hi,

thanks for your reply. The notification about your reply landed in my spam so im kinda late.

I want to upgrade for speed and better performance in general, yes. As far as I checked I should find a 500w motor that would fit in terms of size.
My hope was that I could do the upgrade with the same battery the bike has. The range is not so important (15-30 km is enough), so I figured it might be ok?

So a compatible controller and the motor has to spin faster?
Well, sounds doable...

Thanks,
Karl

PS: these kits at ebikes.ca seem great. I like that I can customize them.
